заъфарон

Заъфарон гиёҳи шифобахши хеле қадима аст.
Saffron is an very ancient medicinal herb.
Аз заъфарон равған ҳам тайёр мекунанд.
They also make oil from saffron.

Bonus:
In Tajik, the third person plural is often used when talking about things that are normally done, so the second sentence would be better translated as “Oil is also made from saffron” or “One can also make oil from saffron”.
